The lollowiiig results were obtained by the first method: — 

 Moisture ... ... 13-50 per cent. 



Total extract ... 37-33 „ 

 Non-tannin ... 6- 16 ,, 



Tannin ... ... 31-17 ,, 



By the cold water extraction alone the results were : — 



Moisture ... ... 13-49 P^"^ cent. 



Total extract ... 31-47 „ 

 Non-tannin ... 3-66 „ 



Tannin 27-81 „ 



III. This bark was taken from trees growing at Grenfell, New South 

 Wales, March, 1909. The trees were only of medium size, and the bark ranged 

 in thickness from 10 to 15 mm. In appearance it resembled the barks of this 

 species collected at other localities and gave the following results : 



Moisture ... ... i2-8o per cent. 



Total extract ... 26-80 ,, 



Non-tannin ... 7-82 „ 



Tannin ... ... 18-98 „ 



IV. This bark was stripped from a log in the Museum, which had been 

 collected at Wellington, New South Wales, September, 1903, and having a 

 diameter of 11 inches. In appearance the bark resembled that of this species 

 from other localities, but it was less rich in tannin; perhaps this was partly due 

 to the length of time that the tree had been felled. The greatest thickness of 

 the bark was 28 mm. It powdered fairly well, but was somewhat more fibrous 

 than the thick bark from Woodstock. The following results were obtained with 

 it:— 



Moisture ... 



.. 13-50 per cent 



Total extract 



.. i8-39 



Non-tannin 



.. 4-28 „ 



Tannin 



.. 14-11 



V. This specimen was collected in Julyj 1909, at Wyalong, New South 

 Wales. It was from a small, very young tree 7 feet high, and i inch in diameter, 

 the bark being taken from a portion 25 mm. (under i inch) in diameter, and i to 3 



feet from the ground. 



The bark stripped very readily. It was mostly smooth, but beginning 

 to crack externally, and to show the commencement of the deeply-furrowed outer
